Carageenan

Carrageenan is a polysaccharide derived from red seaweed that is valued in skincare for its ability to help maintain hydration and support a softer, smoother skin feel. By forming a light, breathable film over the skin’s surface, it can help reduce moisture loss and contribute to a more supple, comfortable complexion.
